recently i upgraded my CPU, Mobo, and RAM but the problem is that i cant get the computer to start up. When i try to start Windows normally (Windows 7) I get the windows load bar and it loads for about 3 or 4 seconds before a blue screen pops up for a split second and then it reboots itself again. When i press F8 and select no automatic restart after error the blue screen comes up and i can read what it says completely. I get a stop error that comes up as follows: ***STOP : 0x0000007B (0xFFFFF880009A9928, 0XFFFFFFFFC0000034, 0X0000000000000000, 0X0000000000000000). My other issue with this is that i dont have the original Windows 7 disk to my knowledge and i dont have the money to get another one after spending all this money on all the other parts that i already purchased. I need help with this issue before i throw this computer out the window and be done with it. I am not sure what do at all and i have no more money to spend on any other parts or anything like that so i need help.
